Cuda 如何解释ptx函数名

编译cuda文件时：

nvcc -arch=sm_61 -std=c++11 -Xptxas -v,-warn-spills --use_fast_math -maxrregcount 128 nv_wavenet_perf.cu -o nv_wavenet_perf_dual

我收到多行注册溢出警告：

我如何知道哪个函数溢出，因为这里显示的函数名对我来说是无法识别的

我只想看到“dualBlock”函数的溢出。这可能吗

CUDA使用最新版本。您看到的是标准的g++风格的函数名。每个主机工具链都附带一个demangler，它可以解析损坏的函数名（最典型的是c++filt）。甚至还有需求者。它们将要求函数名。内部CUDA ABI符号为AFAIK

例如：

_Z20nv_wavenet_dualBlockIffLi64ELi128ELi256ELi2EEv17nv_wavenet_paramsIT_T0_E

要求

void nv_wavenet_dualBlock<float, float, 64, 128, 256, 2>(nv_wavenet_params<float, float>)

void nv_wavenet_双块（nv_wavenet_参数）

我只想看到“dualBlock”函数的溢出。这可能吗

这些警告是由汇编程序ptxas生成的。我所知道的没有办法使这些警告具有选择性。它们不是开就是关。如果单独编译某个函数，就我所知，可能可以控制该调用的汇编器输出级别，但不能在单个编译调用中逐个函数
